在过去几年中，环境DNA（eDNA）技术已被用于监测海洋群落。研究表明，eDNA是监测渔业资源的有效工具。利用eDNA技术分析了长江口鱼类资源的季节变化。2019年长江口四季共采集水样103个，其中2月20个，5月28个，8月28个，11月27个。本研究成功地探测了长江口的渔业资源。我们发现，根据季节的显著差异。结果显示，2019年共发现鱼类59种（2月20种，5月16种，8月5种，11月45种），鱼类种类在四季中变化很大。此外，我们的样本显示，与2018年的eDNA数据和过去几年的传统调查相比，长江口年度鱼类种群存在显着差异。总的来说，eDNA是一个有用的新兴工具，以协助监测和保护长江口鱼类资源。
In the past few years, environmental DNA (eDNA) techniques have been used to monitor marine communities. Research indicates that eDNA is an effective tool for monitoring fishery resources. This study analyzed the seasonal variations in fish resources in the Yangtze Estuary, China, using eDNA. A total of 103 water samples were collected from the Yangtze Estuary across the four seasons in 2019—20 samples in February, 28 in May, 28 in August and 27 in November. Our research successfully detected the fishery resources of the Yangtze Estuary. We found significant differences according to the season. The results showed that 59 species were identified in 2019 (20 in February, 16 in May, 5 in August and 45 in November) and fish species varied widely over the four seasons. Furthermore, our samples revealed significant differences in annual fish stocks in the Yangtze Estuary, compared with eDNA data from 2018 and with traditional surveys from past years. Overall, eDNA is a useful emerging tool to assist with monitoring and protecting fish resources for the Yangtze Estuary.
